The Medicine Wheel by Lane R Warenski

Zach Connors is a man content spending his life in the wilds of the Rockies. However, in a land with no law he must fight renegade white men, hostile Indians, and the wilderness itself to survive. He forges a home in which to raise his family, but to keep them safe it will take more than the might of his guns or the strength of his will. It will take the power of an ancient Medicine Wheel.
